I’m planning for our trip to Aulani and have a long list of what we should bring. I’m a project manager by profession so lists and planning are my jam! But I also know from my research there is a Costco between the airport and the resort. So what are must have items to pack (besides clothes ) and what should we just plan to buy when we get there. Its just my husband and I traveling and we are stopping at Disneyland on our return for 5 days. Thanks in advance for the advice.
